Does iphone test shutter speed, the aperture settings per ASA setting and health of the blades ?

I have Olympus XA2.

May be it can record video of the blades movement and does analysis ? I really dont know.

Yes, iPhones can do slow motion videos, so you can capture the shutter moving.

But it cannot analyze.

I think the frame rate is 240fps. So you would get 1 frame at full opening for the 1/250s setting; 2 for 1/125s, etc. It's worth a try. For the aperture the answer is no. You can estimate the entrance pupil size but that's not accurate.
